Yeast infection (candidiasis) can become chronic under certain conditions (low immunity and diabetes, for example). If you have had candidiasis four or more times during a year, this suggests a recurrent or chronic yeast infection. This type of yeast infection is much more difficult to cure.
To treat a chronic or recurrent yeast infection, it’s necessary to undergo further examination; for example, taking a smear test to determine the fungus species. The results of the tests will help the doctor prescribe the correct treatment and halt the progression of the infection.
